MDD041B-N-100-N2K-050FB0
The MDD041B-N-100-N2K-050FB0 is a compact AC servo motor produced by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. Designed to pair with digital drive controllers, the unit converts commanded current into controlled rotary motion for positioning or speed regulation tasks in automated assembly lines and pick-and-place gantries. It is intended for servo applications that require accurate response during frequent starts, stops, and direction changes. The compact housing also helps the motor fit into machine layouts where installation space around the axis is limited.
The motor uses a centering diameter of 50 mm and standard balancing to reduce residual vibration as the shaft approaches its rated nominal speed of 10,000 rpm. Power and feedback conductors exit on Side B, which helps keep cable routing away from moving machine elements. At standstill, the motor can deliver 1.35 Nm of continuous torque for light holding duty without excessive heat buildup. Position information is sent to the drive through resolver feedback, and an integrated absolute encoder supplies multi-turn data after power cycles. This combination supports stable control during motion and preserves position information for synchronized restart behavior.
For wiring, the motor uses a connector interface. The output is a plain shaft with no keyway or side-B extension, which suits clamping-style couplings and compact gearhead connections. The motor has frame size 041 and length code B, giving it a short body for tight machine envelopes. It is supplied without a blocking brake, so an external holding method is required when the load must remain fixed with power removed. There is no shaft seal, so the motor is better suited to clean environments or to installations that use an added sealing element to protect the bearings from contamination.
